2 Safety Instructions for hot pluggable Modules
Check before every maintenance work on the system:
•If a data backup is required?
•Is a backup required, verify the data recovery which is done by this backup.
•Make sure to avoid any static discharge while working - use a grounding cable and/or antistatic gloves
during installation and removal of hot pluggable components.
•If you are replacing a hot pluggable power supply, unplug the power cable prior to removing the module
from the case.
•Never open a power supply. In power supplies dangerous voltages can still remain even after disconnection
from the power supply. Always send power supplies back to the manufacturer for maintenance.
Exchange of hot-swap components
•Ensure that components which will be replaced during operation, always be treated with the utmost care.
Avoid contact with live components.
•Electrostatic discharge can damage electronic components. For this reason, ensure protection against
electrostatic discharges by wearing anti-static shoes while working with the system.
•Take care when removing and installing the hot-plug modules. Always work with the utmost caution.
Touch the modules only at the edges.
•Place the module out of the box or after removal from the system with the component side to the top on
a grounded and static-free surface.
•Storage of an IMS module must be done in a dry place.
•Installation or removal from hot-swap components only by authorized personnel!

2 Safety Instructions for hot pluggable Modules
2.1 Additional Safety Hints
This manual contains important information for the installation and operation of this device as well as for your
safety. Make sure to read carefully before installing and commissioning the device.
Certain operating conditions may require the observance of additional safety regulations not covered by this
manual. Nonobservance of this manual will lead to a significant abatement of the security provided by this
device. Security of the facility where this product is integrated lies in the responsibility of the installer.
The device must be used only for purpose named in this manual, any other use especially opteration above the
limits specified in this document is considered as improper use.
Keep all documents provided with the device for later reference.
This manual is exclusively for qualified electricians or by a qualified electrician trained personnel who are
familiar with the applicable national standards and specifications, in particular for the construction of high
voltage devices.
2.2 Supply Voltage
WARNING!
This device is powered by a dangerous voltage. Nonobservance of the safety instructions of this manual may
lead to serious damage to persons and property and to danger to life! Installtion, commissioning, maintenance
and operation of this device are to be carried out by qualified personnel only.
The general safety instructions and standards ( e.g. IEC, DIN, VDE, EN ) for installation and work with
high voltage equipment as well as the respective national standards and laws must be observed.
NONOBSERVANCE MAY LEAD TO SERIOUS DAMAGE TO PERSONS AND PROPERTY AND TO DAN-
GER TO LIFE!
The device may not be opened. Repair services may only be carried out by the manufaturer.
Supply lines for this decice must be equipped via an appropriate switch that must be mounted close to the
device and must be marked as a mains switch for the device.
To ensure safe operation supply mains connected to this decice must be equipped with a fuse and a fault-
current circuit breaker according to the applicable national standards for safe operation.
The device must be connected to a protective earth with low grounding resistance according to the applicable
national rules.

2.3 Cabling
WARNING!
DANGER TO LIFE BY ELECTRICAL SHOCK! NO LIVE WORKING!
Wiring or any other work done the connectors particularly when connectors are opened may never be carried out
when the installation is energized. All connectors must be covered to prevent from accidental contact to life parts.
ALWAYS ENSURE A PROPER INSTALLATION!

3 Replacement or Installation of a Hot-pluggable IMS Module
3 Replacement or Installation of a Hot-pluggable
IMS Module
If the system is supplied with an antenna and antenna cable, it is advisable to first mount the antenna in a
suitable location (see chapter Antenna Mounting) and lay the antenna cable.
Please use a Torx screwdriver (T8 x 60) for removal and installation of the module.
1. Follow the safety instructions at the beginning
of this manual!
1. Remove the two marked Torx screws from the
module holder plate or the cover plate of
the empty slot.
2. (Only for an already built-in module)
Pull the module carefully out of the holding
rail. Note that the module is firmly anchored
in the connector block of the housing. You need
a certain amount of force to release the module
from this link. Once the connection to the
connector block of the system’s backplane is
loosened, the module can be easily pulled out.
3. When installing the new IMS module, please ensure that the board is correctly inserted into the
two guide rails of the system housing. Non-observance can cause damage to the module and the chassis.
Make sure that the module is securely locked into the connector block before you fasten the two screws.
4. Now you can put the installed module into operation.

3.1 Important Hints for hot-pluggable IMS Modules
The following points should be strictly observed when replacing IMS modules during operation. Not all IMS
modules are fully hot-pluggable. Of course, it is not possible to replace a power supply unit of a non-redundant
system without first having installed a second power source in operational mode.
The following applies to the individual IMS slots:
PWR: "hot swappable" If you operate your system with only one
power supply, a second power supply must
be installed before removing/replacing it
to keep your system functioning.
I/O, ESI and MRI Slots: "hot swappable".
CLK1, CLK2: "hot swappable" Afer the exchange or the installation of a
clock module a rescan of the reference clocks
(Rescan Refclocks) must be executed in the web
interface menu "System".
CPU: "hot swappable" The NTP service and access to the web interface
are interrupted while the CPU is disconnected.
Also the management and monitoring functions are
no longer available.
RSC/SPT: "hot swappable" The switching function or the distribution of
generated signals is interrupted while the RSC/SPT
is disconnected.
